  • Schottky diode with voltage limiting guard band
    Patent number: 4110775
    Abstract: A metal-semiconductor diode which includes an integral voltage clamping guard band. The guard band is defined by a p-type region disposed in an n-type epitaxial layer which layer contacts the anode barrier metal. The guard band in addition to reducing edge leakage, limits the reverse voltage on the metal-semiconductor barrier to less than its avalanche breakdown voltage. This provides transient voltage protection for the diode.
